Abstract

The invention relates to the technical field of the sensor, and provides a composite angle sensor with a function for measuring multi-turn angle. The composite angle sensor comprises a shell, and an absolute photoelectric angle encoder, a potentiometer and a circuit board which are arranged in the shell; the absolute photoelectric angle encoder comprises an input shaft, a light source, a movable grating and a stationary grating, wherein the input shaft is arranged at an axes of the shell and the movable grating is fixed on the same; the light source is arranged above the movable grating and the fixed grating; the movable grating and the fixed grating are engraved with the absolute codes; the potentiometer comprises a stator and a rotor; the rotor is connected with the input shaft of an elastic coupling; the input shaft can drive the movable grating and the rotor to rotate; the circuit board comprises a sampling module and a micro control unit; the sampling module is electrically connected with each of the micro control unit, the absolute photoelectric angle encoder and the potentiometer. The accurate measurement of the full-scale number of turns can be realized, and the measurementprecision of the multi-turn angle is improved.

Description

technical field [0001] The invention relates to the technical field of angle sensors, in particular to a composite angle sensor capable of measuring multi-turn angles. Background technique [0002] The angle sensor is a sensor that senses the rotation angle of the rotating shaft. It can convert the mechanical linear displacement or angular displacement into a sensing element that has a certain functional relationship with it. , It is also widely used in measuring physical quantities such as pressure, acceleration and liquid level. [0003] The traditional multi-turn angle sensor uses magnetoelectric coding or photoelectric coding to measure the angle and cooperate with the gear transmission structure to measure the number of turns. A battery is installed inside to memorize the current angle information after power failure. The existing defects are: short battery life and difficult to replace, complex gear transmission structure, high precision requirements, and large volum...
